"All down the church in midst of fire, the hellish monster flew, and, passing onward to the quire, he many people slew."
Black Shuck is the name given to a being found primarily in the folklores of the British Isles. The black dog is essentially a nocturnal apparition, often said to be associated with the Devil or a Hellhound. Its appearance was regarded as a portent of death. It is generally supposed to be larger than a normal dog, and often has large, glowing eyes. It is often associated with electrical storms (such as Black Shuck's appearance at Bungay, Suffolk), and also with crossroads, places of execution and ancient pathways.
This model has been successfully printed in Black SF (recommended. Otherwise it's just a dog skeleton).
